Kamal Handbook
Kamal Handbook is the missing manual for the new Kamal deploy tool which lets you run Docker in production with minimal effort.
- Visualize Kamal’s concepts and learn things behind-the-scenes
- Understand Kamal’s configuration
- Deploy practical life examples with confidence
Now in second edition for Kamal 2.
What will you learn?
First, we explain what Kamal is, look how Kamals works on the surface, and go through the first deploy. Then we’ll dive more into Kamal’s server configuration and use the new knowledge for deploying 2 more complex examples. At last, we have a look on logging, debugging, CI/CD, and handling backups.
Foreword

FAQ

The Patron copy contains all editions and might come with early access and additional future bonuses.
Will I get free updates?
You get free updates for a given edition. The Patron copy gets free lifetime updates for all editions.
Is this book just for Rails?
Kamal is framework-independent and so I wrote the book in a general way, only mentioning assumptions about one’s Dockerfile. Bring your Dockerfile and you are good.
Is this only for Ubuntu?
Kamal doesn’t tie itself with any particular Linux flavor so you can use your favourite. The small provisioning examples in the book are tested against Ubuntu 22 LTS.
